Digest authentication in Python?

I'm trying to access pages from my company server with python. The first trail return 401: Unathorized(the server does need domain username/pwd for authentication). And the header content is as follow, and it seems to support 3 authentication protocols, Negotiate, NTLM and Digest, so in my understanding, I can choose any of them, right?

Content-Type: text/html
Server: Microsoft-IIS/7.0
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM
WWW-Authenticate: Digest qop="auth",algorithm=MD5-sess,nonce="+Upgraded+v184080dc2d18fe10d63520db505929b5b5b929ec98692ce010e80d6347b7a35d4027e59e277ac4fe1c257a95196071258a8e0797bf6129f76",charset=utf-8,realm="Digest"

I'm using following python codes, but still got 401 unanthorized error, can anybody tell me how can i achieve it? Should I use NTLM? Thanks in advance!

p = urllib2.HTTPPasswordMgrWithDefaultRealm()
p.add_password(None, self.url, username, password)
handler = urllib2.HTTPDigestAuthHandler(p)
opener = urllib2.build_opener(handler)

urllib2 is the python standard lib, but not necessarily the best for http requests. I would highly recommend checking out the requests package, and you can find an authentication tutorial here:
